目的：对无症状人群行冠状动脉CT血管成像（ computed tomography angiography， CTA）检查，分析冠状动脉粥样硬化及血管管腔狭窄情况。方法对1970例无症状、无冠心病、无糖尿病病史者行冠状动脉CTA检查，了解人群冠状动脉粥样硬化情况，并分析不同性别不同年龄阶段血管管腔狭窄发生情况。结果1970例无症状者，冠状动脉粥样硬化1245例（63．20％）；男性1603例中，可见冠状动脉粥样硬化1069例（66．65％），女性367例中，可见动脉粥样硬化176例（48．09％）；各年龄段血管管腔狭窄均以Ⅰ级发生率最高，男性40～49岁、50～59岁分别为60．17％，54．00％；女性40～49岁、50～59岁分别为56．67％，52．33％。无症状患者，CTA显示管腔狭窄程度＞50％为6．67％。结论 CTA能够无创、准确地一次扫描即提供冠状动脉管腔狭窄、斑块负荷等重要信息。这对无症状非糖尿病患者群、传统风险因素与CT指标存在相关性，但预测管腔狭窄、斑块负荷的影响程度依然有限。

Objective To study the appearance of coronary atherosclerosis in asymptomatic subjects on dual-source computed tomography angiography ( CTA) and determine the morbidity prevalence of coronary atherosclerosis among asymptomatic people.Meth-ods A total of 1970 asymptomatic subjects without prior history of CHD and diabetes underwent coronary CTA.The status of coronary atherosclerosis was described.The differences of luminal stenosis, number of involved branches, lesion involving left main artery, seg-ment involvement were analyzed by CT.Results Of 1970 cases, there were 1245 (63.20%) with coronary atherosclerosis.There are 1069 (66.65%) with coronary atherosclerosis among 1603 males and 176(48.09%) among 367 females.In each age group, grade I was the highest incidence of vascular luminal stenosis(60.17%,54.00%;56.67%,52.33%).Gender and age were associated with the progress of atherosclerotic plaque.Conclusions CT angiography provides important information about luminal stenosis and plaque burden in one scan noninvasively and accurately.In asymptomatic non-diabetic population, the conventional risk factors are correlated with CT findings, but still limited in predicting luminal stenosis and plaque burden.
